R1 and R2
Optical fiber receiver (ST bayonet closure)
R1 and R2 are the receiving optical fiber connectors of the Sync-Transceiver (refer to
The optical interfaces are set to use positive logic (light idle state: OFF) at the factory. Switched-on light is
treated as active = 1 (high). To adapt to systems that use negative logic, a switch is integrated in each input
channel R1 and R2. If you set the DIP switches 1/2 to ON, you switch to negative logic.
